Hemoglobin, the protein found in red blood cells, plays a crucial role in our bodies beyond just transporting oxygen. One of its important functions is facilitating the exchange of gases in our respiratory system. However, hemoglobin also aids in maintaining the body's pH balance and helps buffer against changes in acidity. It even assists in regulating blood pressure and overall cardiovascular health.
If you would like to explore how hemoglobin accomplishes these tasks in more detail, I can explain further.
